WSO2 API Manager 4.1.0网关令牌URL访问404问题求助

The 404 error you're encountering is most likely due to a change in the OAuth2 token endpoint path between WSO2 APIM 3.1.0 and 4.1.0. Here's how to resolve this and other potential checks:

1. Update the Token Endpoint Path #

In WSO2 APIM 4.x, the token endpoint was restructured to follow standard OAuth2 conventions. Instead of using /token, you need to use /oauth2/token. Modify your curl command to:

curl https://testapi-am.example.com:8243/oauth2/token

This replaces the legacy /token path used in 3.x versions.

2. Verify Service and Configuration Status #

• Check if all APIM services are fully initialized. Review logs in <APIM_HOME>/repository/logs/wso2carbon.log to confirm no errors related to OAuth2 or gateway deployment during startup.
• Ensure the HTTPS port (8243) is correctly set in deployment.toml:

  [transport.https]
  port = 8243
  

• If using multi-tenancy, append the tenant domain to the endpoint for tenant-specific token requests:

  curl https://testapi-am.example.com:8243/t/<your-tenant-domain>/oauth2/token
  

3. Confirm OAuth2 Component Availability #

By default, the OAuth2 component is enabled in APIM 4.1.0. If you’ve customized the deployment, verify that OAuth2-related OSGI bundles are active via the Carbon Management Console under Bundle Management.
